CASING FOE LATiZlfiOCKETESL Application filed May 2,1914.

To all whom it 71;.(17/ tie/morn 130. it known that 1, CHARLES .l KLEIN, a. citizen of the United States. residing at lVlilwuukee, in the eolmty of h'lilwaiilree and State of ll iseonsin. hn invented new and i'ise'liul Improvements in Casings for Lump- Sockets, of which he following is a full clear, concise and exact (.lGSCZlpiilOn, rel'er enee being hail to the lieeoinpzinying thew ing, forming a part of this sipeeilic'zetion.

This invention relates to casings for inenrulescent lamp sockets and pendent switches.

The various objects and iiilvantzigee ol :Ehe invention will appear liereina ter in commetion with the description of a. prett'erred emhodiment of the invention shown in the m:- companying drawing, wherein-- Figure 1 is a side View of a lamp socket easing; Fig. 2 is a perspective view of the casing shell; and Fig. 3 is a section-e1 view on the line 3-3 of Fig. 1.

The casing illustrated comprises a. cap 1 and shell 2 arrmwed to telescope together in a conventional manner. Interlocking means are provided to prevent axial separation and relative rotution of the parts when. joined. The means 'llllliitfltQCl of the type (l6- scrihed and claimed in my (to-pending zipplinotion, filed. .l leeeinher H, 1913. Serial No. 807,455, and eonqn-ises a pair of interned beveled catches 3 on the cap and pair of arc-shaped Di'mHlUgS l in the shell.

When the parts of the casing are tele scoped together the cooperating outehes nuton'mticzilly interengage and the rep rim the shell margin so that the olosely encircles catches i i-pass well through the open'in and elfect a secure look. l?urthermore socket base 5 which supports the curl carrying parts is snugly inelosed. within the casin As a result of the smug: lit of the socket parts within the shell. uni-l ol the shellv within the C235. linger eonipre.
